What can you conclude about two integers whose product is negative?
Step 1: For the product of two integers to be negative, one must be negative & other must be positive.
Step 2: Example 1. The product of 3 & -5 is -15 as both integers are of opposite signs.
Step 3: Example 2. The product of -2 & 4 is -8 as both are of opposite signs.
Final Answer: For the product of two integers to be negative both integers must be opposite in signs; one must be positive & other negative.
